Abstract Organic semiconductor single‐crystal heterojunctions (OSSCHs) are engineered by integrating complementary organic crystals to enable ambipolar transport and multifunctional device performance. This review outlines recent progress in the crystal growth, interface physics, applications of OSSCHs, with an emphasis on low‐dimensional structures achieved through controlled crystallization advanced engineering. Innovations control, such as integrated self‐assembly van der Waals epitaxy, have enabled construction defect‐minimized heterointerfaces molecular‐level precision. Emerging strategies engineering, including vertically stacked heterostructures ultrathin 2D molecular crystals, optimized carrier dynamics while introducing unique optoelectronic properties. The band alignment at critically governs exciton dissociation efficiency charge pathways, directly enhancing performance photovoltaics light‐emitting systems. These demonstrate promising across transistors, devices, neuromorphic electronics overcoming inherent limitations unipolar active layers. also highlights current challenges future research directions, emphasizing role OSSCHs advancing fields materials science
